Reviewing a Decade of Research on the “Base/Bottom of the Pyramid” (BOP) Concept
系统回顾2000-2009年间104篇关于金字塔底层（BOP）概念的学术文章，分析该概念在Prahalad最初呼吁后的演变，发现BOP研究日益复杂，跨国企业角色被弱化，并指出未来研究方向。
In 1998-1999, Prahalad and colleagues introduced the base/bottom of the pyramid (BOP) concept in an article and a working paper. This article’s goal is to answer the following question: What has become of the concept over the decade following its first systematic exposition in 1999? To answer this question, the authors conducted a systematic review of articles on the BOP, identifying 104 articles published in journals or proceedings over a 10-year period (2000-2009). This count excludes books, chapters, and teaching cases. The review shows that the BOP concept evolved dramatically following Prahalad’s original call to multinational enterprises (MNEs). Deemphasizing the role of MNEs over time, published BOP articles portray a more complex picture, with wide variations in terms of BOP contexts, of BOP initiatives, and of impacts of the BOP approach. A simple framework for organizing the reviewed articles helps discuss findings, identify the gaps that still exist in the literature, and suggest directions for future research.
